Description
Technical field
The utility model relates to air-conditioning technical field, especially relates to a kind of air-conditioning filter net injection mold.
Background technology
Air-conditioning filter net adopts mold injection molding conventionally at present, steel wire is put into the film chamber injection moulding of mould, but the net sheet of injection mo(u)lding belongs to semi-finished product, the many size ranges that can exceed rack of size of netting, the artificial pruning of net sheet waste material needs that exceeds rack, every mold is equipped with at least specially a people and prunes net sheet waste material, and labor strength is large, production efficiency is low, and cost is high.
Utility model content
Not enough for prior art, technical problem to be solved in the utility model is to provide a kind of air-conditioning filter net injection mold, and the net sheet of its injection mo(u)lding is without pruning, and production efficiency is high.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is:
A kind of air-conditioning filter net injection mold, comprise suitable punch and die, between described punch and die, be formed for the cavity of injection moulding net sheet, described punch comprises punch core rod and is located at the trimming punch in punch core rod outside, described groove comprises die core rod and the trim die that is located at die core rod outside, and described trimming punch and trim die are suitable.
Described trimming punch is provided with step, and medial surface and the step side of described trim die are suitable.
The lateral surface of the medial surface of described trim die and trimming punch is suitable.
The profile of described trimming punch is mutually concordant with the profile of punch core rod.
Distance between the profile of described die core rod and the profile of trim die is less than the distance between the profile of trimming punch and the step surface of step.
The step surface of described trimming punch is provided with protruding cutting edge, and described protruding cutting edge one end face is relative with step side, and protruding cutting edge other end is relative with the lateral surface of trimming punch.
The profile of described trim die and the distance between step surface are 0.5-1mm.
The utility model compared with prior art, has the following advantages:
During mould matched moulds, by trimming punch and trim die is suitable that unnecessary net sheet is cut, the screen pack after injection mo(u)lding is out separated with net sheet waste material, by screen pack taking-up, is exactly directly finished product, no longer needs manually net sheet waste material to be pruned; Trimming punch is done empty avoiding to net sheet waste material and is processed, and net sheet waste material falls into empty avoiding region, and mould does not have mineralization pressure to net sheet waste material, and net sheet waste material can not be bonded on mould, guarantees that net sheet waste material easily takes out; In injection moulding process, realize automatic trimming and blanking, labor strength is little, and production efficiency is high, effectively saves human cost.
Accompanying drawing explanation
Below the expressed content of each width accompanying drawing of this description and the mark in figure are briefly described:
Fig. 1 is the utility model punch structure schematic diagram.
Fig. 2 is the utility model cavity die structure schematic diagram.
Fig. 3 is that the utility model punch and die coordinate cutaway view.
Fig. 4 is the utility model waste material blanking position enlarged diagram.
In figure: 1. punch core rod, 2. trimming punch, 3. die core rod, 4. trim die.
The specific embodiment
Contrast accompanying drawing below, by the description to embodiment, the specific embodiment of the present utility model is described in further detail.
As shown in Figures 1 to 4, this air-conditioning filter net injection mold, comprises suitable punch and die; Wherein, punch comprises punch core rod 1 and is located at the trimming punch 2 in punch core rod 1 outside, and trimming punch entangles punch core rod, and the bolt by side is fixed together both; Groove comprises die core rod 3 and is located at the trim die 4 in die core rod 3 outsides, and trim die entangles die core rod, and the bolt by side is fixed together both.
Between the die that the punch that punch core rod 1 and trimming punch 2 form and die core rod 3 and trim die 4 form, be formed for the cavity of injection moulding net sheet, the borderline phase of the border of die core rod 3 profiles and the rack of screen pack is same, the medial surface of trim die 4 matches with trimming punch 2 and forms the trimming edge of a knife, during mould matched moulds, by the trimming knife edge due in mould, unnecessary net sheet is cut, screen pack after injection mo(u)lding is out separated with net sheet waste material, directly screen pack being taken out is exactly finished product, no longer needs manually net sheet waste material to be pruned.
Wherein, trimming punch 2 is provided with step, and medial surface and the step side of trim die 4 are suitable, forms the trimming edge of a knife.The step profile of trimming punch 2 ends is mutually concordant with the profile of punch core rod 1, and it is corresponding that step profile and the profile of punch core rod 1 are combined with the profile of die core rod 3, and corresponding with the net sheet size of finished product.
Distance between the profile of the profile of die core rod 3 and trim die 4 is less than the distance between the profile of trimming punch 2 and the step surface of step, forms the empty avoiding region to net sheet waste material between trimming punch 2 and trim die 4; Preferably, the profile of trim die 4 and the distance between step surface are 0.5-1mm, and the height in empty avoiding region is reasonable, and net sheet waste material can be not stuck on mould.By the empty avoiding of 0.5-1mm, mould matched moulds completes after cutting net sheet, and net sheet waste material falls into empty avoiding region, and net sheet waste material can not be bonded on mould, avoids waste material to kill on mould, and net sheet waste material is convenient to take out.
On the step surface of trimming punch 2, be provided with for by the protruding cutting edge of net sheet waste material segmentation, protruding cutting edge one end face and step side align, and the lateral surface of protruding cutting edge other end and trimming punch aligns; Projection cutting edge be two of symmetry, or is four of cross symmetry; After mould matched moulds, the protruding cutting edge on step surface contacts with the profile of trim die, and net sheet waste material is cut to multistage, is convenient to waste material and takes out.
Or the trimming edge of a knife of the another kind of structure of the suitable formation of the lateral surface of the medial surface of trim die and trimming punch, net sheet waste material directly falls, and by segmentation, takes out.
By reference to the accompanying drawings the utility model is exemplarily described above; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that design of the present utility model and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
